CHARLES EDWIN BLUE, OF WVHEELING, WVEST VIRGINIA.

MACl-HNE FOR THE MANUFACTURE OF GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 679,664, dated July 30, 1901.

Application filed March 7, 1898. Serial No. 672,889. (No model.)

To coZZ whom it may concern:

Be it known that I, CHARLES EDWIN BLUE, of lVheeling, in the county of Ohio and State of West Virginia, have invented certain new and useful Improvements in Machines for the Manufacture of Glassware; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings,

which form part of this specification.

My invention relates to improvements in machines for the manufacture of glassware, and pertains to that class of machines in which a plurality of traveling molds are used.

One object of my present invention is to provide a machine in which separate and independent molds are moved in succession upon a support or way in contradistinction to having the molds in a fixed relation upon a carrier or movable support.

Another object of my present invention is to so construct a machine that the molds travel in one plane when in an operative position and are returned for a repeated operation by traveling in a different plane.

A further object of myinvention relates to the construction and arrangement of parts, which will be fully described hereinafter and particularly referred to in the claims.

In the accompanying drawings, Figure 1 is a longitudinal vertical sectional view taken on line 1 1 of Fig. 3. Fig. 2 is a vertical transverse sectional View taken on the line 2 2 of Fig. 3. Fig. 3 is a top plan view of the machine. Fig. i is a detached perspective View of the operative mold support or way.

Fig. 5 is a detail plan view of the table or platform carried by the piston T. Fig. 6 is a plan view of the table or platform carried by the piston Q.

Referring now to the drawings, 1) is a base from which extend the uprights c, which support a moldway or support for the molds when they are being operated and which for convenience maybe aptly termed an operative way.

The machine is supported upon the wheels d,whereby it is capable of being readily moved to any desired point.

The operative moldway or support A has at its receiving end an opening B, through which the molds pass, at its opposite end an opening 0, through which molds are delivered, and a supporting portion D intermediate the said openings for supporting the molds in the blowing position.

E is a cylinder supported by a vertical standard 25, attached to the machine in any desired way.

F is a piston within the cylinder, and G a piston-rod connected therewith. The upper portion H of the piston-rod passes through the upper end of the cylinder-head. The lower end of the piston carries a presserhead of the ordinary construction or any other which may be preferred, and this presserhead carries the usual plunger J. The upper end 11 of the piston-rod carries a laterally-extending arm K, having adjustably attached thereto a blower-head L, carrying at its lower end a blower-head M of any desired and suitable construction, or the blower-head may be worked independent of the pressing head by treadle or otherwise.

Situated below the operative way A is a return way or support N, upon which the molds are delivered from the delivery end of the operative way A and are conveyed downward to the opposite end of the return-wayN to be delivered to the receiving end of the operative way in a manner to be hereinafter de scribed.

P is a cylinder situated beneath the delivery end of the return-way N, carrying a piston and rod Q, which has at its upper end a table or platform R, adapted to support a mold. This table It and the molds are provided, respectively, with pins and openings whereby the mold is supported and held against relative lateral movement in respect thereto. Situated below the opposite end of the returnway N is a cylinder S, carrying a piston and rod T, having at its upper end a platform or table U, also constructed with pins or openings adapted to cooperate with the molds, as previously described in respect to the platform R, for holding the molds against/relative movement upon the platform when in position thereon. A pipeV establishes communication between the upper end of the cylinders S and P, and a pipe W establishes communication between the lower ends of the cylinders. Situated within these pipes V and W is a valve 6, moved downward by means of a treadle g and normally held upward through the medium of a surrounding spring f. As indicated in Fig. 1, when the valve is in its upward normal position air, gas, water, or other source of power is admitted, through the pipes ,c and W, to the lower end of the cylinders P and S and their pistons forced upward; but when the valve 6 is forced downward through the medium of the treadle or foot 9 air is admitted at the opposite end of the cylinders through the pipes d and V and forces their pistons downward, or air may be used only in the up movement and gravity perform the downward stroke.

The return-way N, I have shown in the form of an inclined plane, consisting of two parallel series of rollers a, between which the cylinders S and P are situated, as clearly shown in Fig. 2. The object of having the return-way N on an incline is to cause the molds when lowered on the upper end thereof to move downward thereon by gravity to the opposite end to be carried up and delivered to the operative way A. I do not, however, consider this form of return-way as essential, and I do not therefore limit myself thereto, for any other form of support, way, or means of transporting or carrying the molds from the receiving to the delivery end of the return-way, or any means situated below the operative way whereby the molds are received from the said way and transported and carried to the opposite end thereof for the repeated operation, is within the scope of my invention.

The opening B of the operative way or support A is provided with supporting latches or members ct, adapted to spring under the bases of the molds when they are elevated through the opening, and the delivery-opening O is provided with corresponding latches, which are forced backward bythe platform U when it moves upward through the opening 0.

Any desired form of mold may be used; but for the convenience and the better understandingof my present invention I show molds consisting of a press and a blow mold, the press-mold consisting of two parts 7" and the blow-mold of two parts .9, the parts being adapted to be separated and brought together for the purpose of forming either a press or a blow mold. The molds forming no part of my present invention, it is not necessary to show any particular form of mold or any particular means for operating the molds, so long as it is understood that the molds consist each of a press and a blow mold.

A pipe 1' communicates with the lower end of the cylinder E, and the pipe h with its up and resser-head normally upward. The lower end of the valve-rod j is provided with a handle m, by means of which it is drawn downward for admitting air to the upper end of the cylinder.

The mode of operation is as follows: The presserhead being normally upward, as shown in Fig 2, and the press-mold closed, a charge of molten glass is dropped within the mold. The handle 1% is then drawn downward, which admits the motive power above the piston, causing the plunger to descend and press the glass in the usual manner. The releasing of this handle causes the withdrawal of the presser-head to its normal position. (Shown in Fig. 2.) The presser or operator then opens the press-mold and closes the blow-mold around the depending mass of glass. The treadle g is then depressed, which admits air, gas, or other material above the pistons T and Q, causing them to be forced downward, which lowers the discharge-mold upon the incline. The mold then by gravity moves to the lower end of the incline and is stopped in the proper position over the cylinder Pthrough the medium of a stop a. The operator then moves the mold from the pressing to the blowing position and in doing so forces'the preceding mold from the blowing position to the discharging position,which is held by means of the catches in the opening 0. The operators foot is then removed from the treadle g and the two pistons ascend, the piston Q carrying the mold up through the feeding-opening B upon the operative way A, and it.is caught by the catches in said opening. The simultaneous movement upward of the piston T through the medium of its platform U forces the catches out of contact with the mold in the discharging position, and the machine is ready for a repetition of the operation. The bases of the molds being either in direct contact, as shown in Fig. 1, or through the medium of shoulders or projections, the movement of the mold from the pressing to the blowing position forces the mold from the blowing to the discharging position, and the mold in the discharging position striking the rear end of the way A limits the movements of the molds and causes them to be in the proper relative position to receive the pressing and the blow ing heads when they are caused to be lowered, the two heads being situated a distance apart equal to the width of the molds, as will be readily understood.

From the preceding description it will be seen that a simple machine is produced and one capable of rapid manipulation.

I do'not limit myself to the construction here shown forreturning the molds from the delivery end of an operative way to the receiving end of a return-way, for this may be varied without departing from the spirit and scope of my invention, which essentially pertains to any means whereby the molds are taken from the delivery end of the operative way and returned to the receiving end thereof for a repeated operation.
